Description

The QDD-400G-SR8 is a 400GBASE-SR8 QSFP-DD optical transceiver from the Arista 400G optics range. It is built for short-reach 400G links inside the data centre over parallel multimode fibre, such as leaf-spine and top-of-rack to aggregation connections.

It runs 8 lanes of 50G over 850nm multimode fibre through an MPO-16 APC connector. Reach is up to 100m on OM4 parallel fibre and 70m on OM3. This is the non-channelized SR8 version, specified for parallel OM4 cabling with an MPO-16 APC interface. Maximum power consumption is 12W, drawn from the host switch port with no external supply. Transmit power is -6.5 to +4.0 dBm per lane and receive power is -8.4 to +4.0 dBm per lane.

The module fits Arista QSFP-DD ports and is hot-pluggable. Arista also lists SR8 optics in OSFP form as OSFP-400G-SR8, and the related QDD-400G-SR8-C variant adds support for 8x 50G-SR and 25G-SR channelization.
